Miko Posted July 26, 2009 Share Posted July 26, 2009 Hi, I'm testing a function that should return an array containing 2 or more vars. But seems that I did something wrong because when I echo the function it gives me 'Array' <?php $test1 = 'test1'; $test2 = 'test2'; function Return_Test($test1,$test2){ switch($test1){ case 'test1'; $test1 = 'testbla'; break; case 'test2'; $test2 = 'testbla bla'; break; } switch($test2){ case 'test2'; $test2 = 'yipie'; break; case 'test2'; $test2 = 'youhou'; break; } return array($test1,$test2); } ?> <html> <head> <title>Hello</title> </head> <body> <table> <tr> <td><?php echo Return_Test($test1,$test2); ?></td> </tr> </table> </body> </html> What did I do wrong here?

vineld Posted July 26, 2009 Share Posted July 26, 2009 You can not echo an array. Well you can of course but then it will display Array as you mention Either loop through its values or use print_r.

Miko Posted July 27, 2009 Author Share Posted July 27, 2009 Hi, thanks for your answer. I've tested it with a loop: <?php $test1 = 'test1'; $test2 = 'test2'; function Return_Test($test1,$test2){ switch($test1){ case 'test1'; $test1 = 'testbla'; break; } switch($test2){ case 'test2'; $test2 = 'yipie'; break; } return array($test1,$test2); } $return = Return_Test($test1,$test2); ?> <html> <head> <title>Hello</title> </head> <body> <table> <tr> <td><?php foreach($return as $key => $value){echo $value."<br />"} ?></td> </tr> </table> </body> </html> So this works great! But now I need to build this into another php file (functions.php) and in my index.php I should echo or print out the foreach loop, but without coding the loop in the index.php, normally I could do this with Smarty, but this unfortunally not an option is there another way?
